03 CTS - Engine Wiring Harness

I have the same issue as many others have with "Reduced Engine Power" issues on my 03 CTS. I ordered the Engine Wiring Harness that fixes the issue but I cannot find a guide anywhere to installing it. Does anyone have a link or a walkthrough on how to replace the Engine wiring harness?
